Long before the solar observing revolution began, there was Thousand Oaks Optical. Founded more than 30 years ago, Thousand Oaks Optical products now fly above the Earth in NASA's Space Shuttle and serve on the ground for users such as ABC, BBC, CBS, NBC, NOVA, The Discovery Channel, National Geographic and most major universities and observatories throughout the world. Originally located in Thousand Oaks, California and open for business in 1979, this small staff of dedicated professionals have produced literally tens of thousands of solar filters over the years. No wonder millions of solar observers world wide know the Thousand Oaks Optical name!
Thousand Oaks Full Aperture Glass Solar Filter
Thousand Oaks Solar Filters are an observing standard. The Thousand Oaks Type 2+ Glass solar filter was created from high quality hand selected glass which is in turn coated with the exclusive metallic Solar II Plus - simply the most durable on today's market. Thin layers of vacuum-deposited nickel and chrome are applied on the inside surface of the glass substrate, keeping the coating shielded from damage during use. Thousand Oaks Solar II Plus coatings reject 99.999% of the solar energy spectrum - from ultra-violet to infrared. This ensures complete safety for both your eyesight and your telescopes optics! The glass filter elements are then placed into a polished friction-fit spun aluminum cell which is custom tailored to your telescope's outer aperture diameter specifications. A wide exterior cell band is then lined with supplied self-adhesive felt strips for a secure fit. This design helps to prevent heat from building up inside the telescope tube, protecting its exterior and interior components. No danger of a cracked mirror or eye damage... If handled with care, your Thousand Oaks Solar Filter should last a lifetime! Providing a aesthetically pleasing yellow-orange solar image against a black background sky, your Thousand Oaks Type 2+ Filter will show dark umbra and dispersing penumbra sunspot regions, as well as convection-cell granulation on the Sun's surface.

- Super sharp!
Purchased the 190mm ID 1000 Oaks Type 2+ glass filter for my NexStar6SE to view the October 2014 partial solar eclipse. Performance was excellent. Resolution was super sharp and the orange color was very pleasing. I did add three small foam pads at equal distance around the inside of the filter housing to get a snug fit on the 6SE, however, hence the 4 star rating on assembly. I might suggest checking with OPT or 1000 Oaks to see if the next size down would be a better fit if you have a 6SE or similar size scope. But no complaints on the performance of the filter. Absolutely first rate.
